Nintaijutsu

Nintaijutsu (忍体術; Literally meaning "Ninja Body Techniques") is a term used to describe the fighting style used by the Hanabi Shinrai and many others. A combination of ninjutsu and taijutsu , the user uses nintaijutsu by first surrounding himself with the Lightning Release Armor or a similar technique. This augments the strength of his physical attacks, making them more deadly. His speed and reflexes are also increased.
